The blue curve represents \(y=f(x)\). The red curve represents \(y=g(x)\).


What equation expresses the function transformation?

We see the points are transformed vertically, so we are expecting the operation outside the argument. We also remember that vertical transformations are "normal".

In this case, we see from blue to red, the points have stretched away from the horizontal axis by a factor of 2. In other words, the coordinate transformation is:

\[(a,b)\to \left(a~,~2\cdot b\right)\]

So, the correct answer is:

\[g(x)=2\cdot f(x)\]

It might help to visually check all the following:

\[g(-10) = 2\cdot f(-10)\] \[g(2) = 2\cdot f(2)\] \[g(4) = 2\cdot f(4)\] \[g(5) = 2\cdot f(5)\]
